Original application filed January23, 1915, Serial No. 3,959. Dividedand this application filed June 14,

Toedll whom it ma concern:

vented certain new. and useful Improvements ficat-ion. I

Myinventlonrelates to an improvemen 1n plows having for its ob ect toprovldea novel and efiect-ive manner of attaching the Y plow standard tothebeam so as'to transfer to the beam, rather than to the bolts thatconnect the standard thereto, the thrusts and strains to which the beamis subjected in service.

In a pending application Serial No. 3959, of which this is a divisionalapplication, I have shownand claimed certain novel means for themounting of the plow point and,if.

desired, a sweep upon a standard formed by a bent bar of singlethickness so asto reduce to a minimum the obstruction offered bythestandard in' plowing. One object of my present invention is toprovidemeans for fastening a standard of single thickness to the beamsothat the latter will to a large extent reinforce and securely holdthestandard therein andwill at the A same time permit its adjustmenttovary the angular disposition of the plow point relative to the beam forplowing at different depths: I I

In the accompanying drawings I have illustrated-what I regardasthepreferred: embodiment of the principles upon which my present inventionis based, but it is to be understood that I do not intend thereby tolimit myself to the exact construction and arrangement of parts shown.

Referring to the drawings: Figure 1 is a side elevation of the plow beamwith the standard connected thereto and shown in one of its adjustedpositions. Fig. 2 is a similar View broken away to show the standard 7in full elevation and in a different adjusted position. Fig. '3 is across sectional'view on the line of Fig. 1. I 1

Similar reference numerals refer to similar parts throughout thedrawings. p

In the preferred embodiment of my. in-

vention which isillustrated in the drawings the plow is shown with awooden beam 1 having handlesQ of usual construction, the

beam havingin its underface a narrow,'ver-' Serial na'easss.

tical, longitudinally disposed slot 3 extendisformed preferably of asingle bent metal bar having at its forward end an upturned curved lug 6in which I provide a series of bolt holes 7. The upper portion l of thestandard which fits in the slot 3 is of substantial length and ispivotally connected at 1 its rear end tothe beam by'a cross bolt 8disposed near the rear end of the slot 3. The rear vertical edge of thelug 6 and the series of bolt holes 7 therein are both struck on arcsfrom bolt 8 as a center and the rear wall 9 of the vertical extension ofthe slot 3 is struck on a similarcurve. A bolt 10 is passed through thebeam and through one of the bolt holes 6 to attach the forward end ofthe standard to the beam adjustably so that the plow point 11 may be setat the desired angle. It will be noted that the standard is of singlethickness'and' its foot portion is brought forward on a gradual curve tothe'point of attachment thereto ofthe plow point 12. The rear end wall13 of the slot 3 is "curved so that when the standard is set in theposition shown in Fig. 2, the rear curved edge of the'standard beyondits pivot 8 will have an extended bearing. The holes for the bolts 8 andare designed to leave suflicient play to permit the standard to take itsbearing against the beam in the manner which will now be described.

It being my purpose to so connect the standard tothe beam that thelatter takes practically all of the strain from the fastening bolts, itwill be noted that the rear curved face of the extension lug 6 will, inall operation positions, take a firm and solid bearing against thecurved wall 9 of the slot, thus'relieving the bolts of all draft strainon the standard exerted rearward of the beam. It will be noted that theupper edge of the standardsection t will bear solidly against the topwall of the slot 3 above'tht bolt 8, thus taking'the up thrust of thestandard off of the bolt 8. The rear curved wall 13 of the slot isdesigned to afford a greater bearingsurface forthestandard whenadtobrace the standard not only against up thrust but also againstrearward thrust slot 3 causes theside Walls of the slot to when itsvertical lug 6 bears-only its ex treme upper end against the wall '9.The manner in which the standard fits into the brace the Standardagainst lateral thrust.

Having thus described my invention, what I claim as'new and deslre tosecure by Let ters Patent, 1s:-

.1. In a plow, the combination with a; beam, of a vstandard adjnsta'blyconnected to the beam and formed by a-bent'v metal bar of singlethickness, said bar having an upper portion of substantial length andsai'd 'beam having a longitudinal bottom slot which" snugly. receivessaid upper portion-of the meansto pivotal-1y connectsaid standard tothe'beam. and abutting portions'onthe-beam' aco pies et this patent maybe obtained for standard. and braces it against lateral strain,

and standard which are adapted tosustaintheth'rust strains of thestandard.-v Y

where its depth is increased by a vertical extension of the slot, astandard seated insaid slot and pivoted near thewrear end thereof tothe'beam, a vertical extension on the forward end of the standard whichis adapted to project into said vertical exten sion of the slot, therear edge 01? said vertical extension on the standard being-struck on:an are from the pivot of the'standardas center, and means to fasten theforwa-i'd end otthe standardvin adjusted positions in the slot,;sa1d-n1eans being adaptedtopenmit the rear edge-of said standardextension-tobear against the-rear Wall ofthe vertical eXten-- sion oftheslot.
